According to a New York Times live blog of Saturday's event in Omaha, Buffett in response to a question about Apple and Google said they are both “huge companies that make a ton of money,” but that he’s reluctant to invest in either of them. Nor would be bet against them. Buffett says he sees less risk in IBM shares, in which Berkshire has invested.

“The chance of being way wrong about I.B.M. are probably less than being way wrong in Apple or Google," he said. “I just don’t know how to value them.”

Meanwhile, Buffett told CNBC on Friday that he has no plans to buy shares of Facebook - really, did you think Warren would want to buy shares of a company that is going to come public trading at like 100x earnings? On the other hand, Buffett said the current state of the tech investing environment has little in common with the bubble that formed in 1999 and 2000. “It is not a bubble ... this is not what we were seeing in late 1999 all the way into 2001," he said. "We aren’t in any bubble phase of anything."

Update: CNBC's Becky Quick tweeted that Buffett told her he spent "hours" advising Facebook CEO Mark Zucerkberg about the company's upcoming IPO. Betcha only one of them wore a hoodie.
